Is this relevant? Please disregard if not.
Some years ago the Physics and Architectural Design departments of a university I was associated with called for volunteers to undergo listening tests with respect to design of audio studios. I signed up out of interest, despite the fact that I was then in my early 60s. They welcomed this because as one researcher said, not all potential listeners are 23 year-old golden ears.
I was told that one test involved speaker positioning for hearing high frequency sounds. I was to judge the audibility of a 10kHz signal at various speaker positions, and would then be subjected to 14, 18, and 22 kHz signals from blind speaker positions behind an acoustically transparent curtain.
Unfortunately I couldn't do this test because I couldn't hear anything at even 10 kHz.
Some months later I was told that this was in fact an honesty test. No signals whatsoever came from the speakers. Yet all subjects except for me claimed to hear the 14 and 18 kHz "signals", and a significant number "heard" 22 kHz. Make of this what you will. But I never heard of any outcome or publications resulting from this research - perhaps the finding that they had but one reliable subject, who was too old anyway, had something to do with this.
